FERTILIZER ATTACHMENT FOR PLANTERSfl Filed Nov. 19, 1955 2 Sheets-Sheet 2 qln venlor N OK F. L Green weZZ' K r UNITED STATES PATENT orr Patented a. 19, 1931 Z 096 29gi 2 Claims. (Cl. 111,-?) I j V This invention relates to a fertilizer attach ment for planters, the general object of'the invention being. to provide \means for depositing fertilizer into'a furrow at spaced points in said can be placed in the moist parts of the furrow in the usual manner.

In carrying out my invention I provide a container l for the fertilizer and I mount the con- 0 furrow and at such places in the furrow where tether 0n e ear pa f e instrument through 5 seedis deposited by the planter or where water e ns of e p bracket A a l eis deposited by plantersiused with the placing of ceiver ll depe ds m t lower p of the plants in a row, I h container and the usual perforated plate l3 con- 'Ihis invention also consists in certain other trelS 21 Op n e bottom 1 t COH ai er features of construction and in the combination l5 which is in communication with the receiver 10 I and arrangement of several parts, to be hereinso that by t rotation of this plate a t n after fully described, illustrated i th a amount offertilizer passes from the container panying drawings and specifically pointed out in into the reeeiVeh s plate I3 is Ope in the appended claims, any suitable manner from a shaft H) which is- In describing the invention in detail, reference driven o t e aft l2 t o h means of the 15 will be had to the accompanying drawings where- Spmckets and Chain Shown generally at 0- A in like characters denote like or corresponding flexible tube 2| leads from e bott m 01 the reparts throughout the several views, and in CeiVel to a point d ly in r ar of the whiclue outlet of the spout 5 so that the fertilizer drop- Figure 1 isa vertical longitudinal sectional e through the tube 2| l be p s e in 20 view showing the invention applied to a plant that part of the furrow receiving the water. which deposits water at spaced points in the A gate Valve 2 controls the w of e t furrow lizer from the receiver l1, said gate being atg 21 area; View of Figure 1 tached to a shaft 23 journaled in the receiver e Figurev 3 is an elevation with parts broken away d having one end passing beyond the same as 25 from th f til e tt t said one end receives an arm 24 having a plu- In th e drawings t tt A indicates the rality of holes 25 therein, any one of which is wheel supported frame of a planter which inaadapted to i e a pin 26 passing through the cludes the reservoir I, the furrow opening means rear end of a rod 2? which has its front end 2 t valve 3 for ontrolling t flow of Water connected by a pin 28 to an upright 29 attached 30 from the hose 4, leading from the tank or reserto an arm of the Shaft The upright has a voir to the nozzle 5 and the actuating means for plurality of holes 39 therein, any One Of Which the valve.

Thus water is deposand in this case the parts are so arranged and ited'at intervals in the furrow. so that plants adjusted as to cause a portion of the fertilizer 55 to be deposited at substantially the same place in the furrow that the seeds are being deposited.

By removing the pins 26 and 28 to release the trip rod 21, the device Will then act to broadcast the fertilizer in the furrow so that the invention can be used for placing the fertilizer in a furrow when planting beans, carrots and the like.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What is claimed is:-

1. A fertilizer attachment for a planter comprising a reservoir, a hose leading from the reservoir to the rear of the planter, a nozzle secured to the rear end of the hose, a valve controlling the flow of water from the hose, a rock shaft for operating the valve, means for rocking the shaft, an arm having openings and attached to the rock shaft, a fertilizer container mounted on the rear of the planter frame, a receiver communicating with the container, a flexible tube leading from the bottom of the receiver to a point immediately in the rear of the nozzle, a gate mounted Within the receiver for controlling the flow of fertilizer, a second arm having openings and secured to the gate and journaled in the receiver, and means for selectively timing the opening and closing of both the valve and the gate relative to each other, said means comprising a rod having each end adjustably secured to one of the arms to connect said arms.

2. A fertilizer attachment for a planter comprising a reservoir, a hose leading from the reservoir to the rear of the planter, a nozzle secured to the rear end of the hose, a valve for controlling the flow of water from the hose, means for actuating the valve, said means comprising a rock shaft mounted on the frame of the planter, an arm having one end secured to the rock shaft, a rod connecting the valve with the other end of the arm, a second rod secured to the arm and to the first-mentioned rod at the junction of the first-mentioned rod and the arm, an adjustable projection mounted on the second rod, a rotatable shaft mounted on the frame and driven by the rotation of the rear axle of the planter, and roller arms secured to the rotatable shaft for engagement with the projection on the second rod, a fer-' tilizer container mounted on the rear of the planter frame, a receiver communicating with the container, means controlled by the rotatable shaft for determining the amount of fertilizer passing into the receiver, a flexible tube leading from the bottom of the receiver to a point immediately in the rear of the nozzle, a gate mounted within the receiver, an arm secured to the gate and journaled in the receiver, a second arm attached to the rock shaft, both arms having openings therein, a third rod having each end adjustably connected to one of the arms to connect said arms, whereby when the roller arms engage the projection on the sec- 0nd rod, the opening and closing of the valve 7 arms.
